D343W不銹鋼蝶閥概述
D343W不銹鋼蝶閥(又稱不銹鋼翻板閥)通常采用三偏心多層次金屬硬密封結構球盟会_注册,被廣泛用于介質溫度≤425℃的冶金球盟会_注册、電力、石油化工、以及給排水和市政建設等工業管道上,作調節流量和載斷流體使用球盟会_注册。該閥采用三偏心結構球盟会_注册,閥座與碟板密封面均采用不同硬度和不銹鋼制作球盟会_注册,具有良好的耐腐蝕性球盟会_注册,使用壽命長。
D343W不銹鋼蝶閥是指關閉件(閥瓣或蝶板)為圓盤,圍繞閥軸旋轉來達到開啟與關閉的一種閥,在管道上主要起切斷和節流用。蝶閥啟閉件是一個圓盤形的蝶板,在閥體內繞其自身的軸線旋轉,從而達到啟閉或調節的目的。蝶閥全開到全關通常是小于90° ,蝶閥和蝶桿本身沒有自鎖能力,為了蝶板的定位,要在閥桿上加裝蝸輪減速器。采用蝸輪減速器,不僅可以使蝶板具有自鎖能力球盟会_注册,使蝶板停止在任意位置上球盟会_注册,還能改善閥門的操作性能。

D343W不銹鋼蝶閥的特點能耐高溫,適用壓力范圍也較高,閥門公稱通徑大,閥體采用碳鋼制造,閥板的密封圈采用金屬環代替橡膠環。大型高溫蝶閥采用鋼板焊接制造,主要用于高溫介質的煙風道和煤氣管道。
